Energy-saving and compact technology to reproduce various types of natural environmental conditions with high accuracy

This control technology uses a direct expansion system to further reduce environmental impacts. It achieves excellent controlling performances and reproduces natural environment conditions in test chambers with high accuracy while saving energy and space.


  • Accuracy in temperature control as high as ±0.5°C (HVAC outlet temperature).
    (Average temperature control accuracy is ±1 to 2°C).
  • 45% better energy saving than the conventional energy system with our unique technology for the compressor inverter control.
  • Non-stop and single-step control operations with the inverter control and the hot gas bypass control.
  • Quick response to changes of room temperature settings from high temperature to low temperature, etc.
    (Example: Cooling down at the pace of -1°C per minute of the temperature variation)
  • Ductless and space-saving in machinery chambers through the introduction of the unit cooler system.
    (Example: Saving spaces by 10 m2 approximately with the class of 30,000 m3/h)
